We Shape Our Tools?

Well I have found a blog which has everything I want, at the moment that is. http://misterlamb.blogspot.com Jimbo Lamb's a maths teacher, found his stuff through http://www.slideshare.net . SlideShare is A-MA-ZING!! I seem to have joined up to so much stuff in the last 48 hours and have just found these last four sites, pretty fun, useful stuff, http://prezi.com for doing presentations, highlight certain parts of images, have a play, fun. http://www.preceden.com/ for doing timelines. http://quizlet.com/ for making up flash cards, with chances to practise beforehand. http://yodio.com/ for adding voice to your photos, free, use phone etc. Where to from here? I think I'll find quizlet.com useful soon, maybe even this week if I can find the time to work with it. So you guys, what have you found that interests you in all this stuff?
